## AI overview

Google DeepMind and GovTech Singapore describe an on-device scam detection system for messaging platforms. It screens inbound messages with a lightweight classifier, then uses a fine-tuned Gemma model to evaluate conversation context. Training took place in a managed GCP environment using anonymized datasets, and the article says the system was tested against synthetic dialogues and local corpora. The approach is presented as a way to detect scams while keeping chat data on-device and preserving end-to-end encryption.
